What about Superior Wall - precast foundations. We are building a new high end home about 1/2 mile from a river inlet in Red Bank NJ. Basement floor will be about 10 feet above water table, good drainage away from house. My main concern is the Builder wants to use Precast because it's cheaper and he doesn't have to wait for concrete guys. (current wait time is 3 to 6 months) I'm unsure about reliability and durability, cost generally not a problem (within reason).

Superior Walls is a great system.

No footers required.

Already insulated.

Trucked and craned to location and placed usually in one day.

Do it if they are engineered properly and your code allows it.

We live a house with superior walls foundation installed about 3 years ago. I think you should be concerned about the following. First, the builder must install a drainage system in accordance with Superior's specifications. This means that it must use the correct size of washed gravel for the footer, the correct size drainage tubing, and wrap the drainage tubing with at least 4" of filter. The filter will prevent silt and dirt from entering the draining tube, clogging it, and rendering it useless for draining water away from your basement. The sump pump is useless because the water is not rising up to the sump pump pit, but rather entering the basement before draining below the basement. If it is not too late I would also ask the builder to line the intersection of the foundation with the basement floor with a membrane that would re-direct any water away from the floor. We are experiencing water seepage in the basement with a relatively new foundation because water does not perk down to the gravel footing and flow into the drainage. I think this is because the builder did not use a filter, or installed it improperly.

Also, ask whether the walls are delivered with styrofoam. Styrofoam is a good sound insulator, however, termites love it as much as wood and will find their way into it in no time flat. Watch for termite mud tunnels if the walls with styrofoam are already installed.

Otherwise, Superior Walls aren't that bad.
